nuroma'ric srnmxnme DEVICE.

"'5 Missouri, have invented certain new and v usefullmprovements in Automatic Sprinkl'in'g Devices; andI do declare the following to be a full, clear, andexact description 'of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters .and figures of reference marked thereon, which form a part of this specification.

This invention relates to improvements in sprinkling devices for streets, parks, lawns, etc., and the invention has for its object to provide in a sprinkling system, a sprinkling apparatus which is ralsed above the surface of the street, park, lawn or the like and is maintained in such elevated position during the sprinkling operation and automatically recedes into its normal inoperative position immediatelythe sprinkling operation ceases.

. A'further object isto provide for efiectively guarding against the sprinkler or sprayer being obstructed or choked by the dirt from the street or road-way, which would accordingly render the sprinkler inoperative untilthe obstruction should be removed.

' actuated by the water pressure in order to raise the same into proper operative position and which is so constructed and arranged as to automatically recede to a point in line with the plane or surface of the street, park, lawn, etc., in which the sprinkling device is employed.

-' The invention further consists in certain other novel details of construction. and in combinations of parts, all of which will be first fully described and afterward specifically pointed out in the appended claim.

Referring to the accompanying drawing:

Figure 1 is a vertical sectionalview through a sprinkling device-constructed in accordance with this inventiom Fig. 2 is a transverse sectlonal view taken on line- 2-2 of Fig. 1., Fig. 3 is a transverse seetional view taken on line 33 of Fig. 1.

which; 1 indicates a plate which is preferably square in plan threaded centrally at 2 to receive the threaded casing 3, the said casing 3 being provided with a shoulder 4 to bottom against the under surface of the plate 1 in order to'provide a rigid and durable construction. As will appear from Fig. 1 the casing 3 is provided with a long central cylindrical bore 5 and a lower enlarged bore or chamber 6, a shoulder 7 being pro- 'vided at the junction of the two bores as will appear from .an inspection of the ac-- companying drawing. The bottom end of the casing 3 is threaded to receive a reducing coupling 8-by.means of which the device is connected to the water supply, while the upper face 9 .of the casing 3 is provided with a central depression forming a chamber 10 to receivea sprinkling nozzle 11 in the manner which will be presently described.

Referring particularly to Fig. 1, 12'indicates the upper portion of the automatically operated nozzle which is provided centrally with a cylindrical bore 13 and on its uppefi end with a flange 14, said nozzle 12=being internally threaded at 15 to receive its lower member 16 which is externally threaded at 17'. By means of this construction the length of the nozzle can be increasedor diminished in order to adjust the extent of plane or surface of the plate 2.

18 indicates a lower piston like member which as will appear from Fig. 2 is webbed at 19 to allow water entering the chamber 6 to pass through the same, the said piston like member 18 carrying a central stem 20 leaving at-its upper end a sprayer-member proper'of disk formation. 21, said stem .20

vided around the stem 20 so asto freely permit the water to pass upwardly through the nozzle 12 when the device is in operation.

The lower piston like member 18 is beveled I as at 24 and adapted to engage the shoulder 7 of the nozzle casing 3 t0 providea stop against excessive upward movementof the 1 nozzle 12.. V

It will be observed that, by providing the member 20 with the disk sprayer-member lifting of the spray nozzle 11 above the With this object in view the invention consists in the novel construction and ar- 35 rangement of the'no'zzle or sprayer which i d f tion to the smooth or unbroken surface of a v 21 and the member 12 with the flange 14' by dirt from the street. It is further observed that the water, when turned on, will have theeflfect; to first separate. the disk sprayer-member 21 fromthe member 14, "thus putting the sprinkler or sprayer in operation, and that subsequently the nozzle 12, 16 receives an outwardly thrusting movement, thus elevating the same together With the sprayer member 21 in its open position as indicated in Fig. 1.

. Having' thus fully; described the several parts of this invention its-operation is as follows: The device being applied in a street,

roadway,v park, lawn or the like withthe plate 1 flush with the surface of the street,- roadway, park, lawn or the likelthe disk sprayer-member 21 on the stem 20 lies fiat against the flange 14 of the. nozzle 12, said "disksprayer-member 21 and flange 14 lying within the recess or chamber 10 in the upper face of the nozzle casing 3 in-such manner that the upper surface of the disk sprayer member 21, is flush With-the outer surface of thejsurrou'ndingplate 1. fln ,this position the device presents no obstacle or obstrucstreet, roadway, park, lawn 015 the -like and as such isnot an impedimentptotravel or dlSk sprayer-member 21 aUpredeterminejd distance above the flange "14 of thecnozzle 12.1 Upon-the raising of the disk sprayer-member 1f 21 into this position Whichis as shown in Fig. 1' ffugther" pressure of ,the {water supply" causes the piston like member 18 to be raised" '1 thu 12 and the disk; 21 into position shown in full linesih Fig.- p Witnes ses:

.1. The water passing upwardly throughthe 50 nozzle 12 is caused'to impinge against the un-'- intoposition shown in the flanged end of the nozz e trafiic orunsightly in lawns; parks or the i like. When it is desired to'bring the sprin -'kling device into operation the'wa'ter, supply. is o'pened 'to' the. lower chamber '(i of the; "valve-i casing 3- and immediately jthe water. passesfuparound the stem 20 raising the der surface of the disk sprayer-member 21 and be forced out between the said disk and the flanged end 14 of the nozzle 12, thus causing the Water to leave the device in a fine spray which by reason ofthe construction herein 1 21 down into the recess or'chamber 10 in the face of thenozzle casing 3. a 7 Having thus described the several parts of this invention What I claim as'new and desire to 'secure'by Letters Patent of the United States is sprinkler ofthe type described, including a casing having a bore extending therethrough, said bore beingenlarged at its lower end, said casing being"arranged for application to a Water-supply under pressure, a nozzle having an upper-end flange, said nozzle being arranged within the bore of said casing, the lower end of said nozzle having an enlargement received by the borecomprising a sprayer-member proper of disk-formation and' a stem depending centrally from v said sprayer-member proper lower-end "controlling member also received by said bore-enlargement of the casing, said disk sprayer member being arranged to be initially separated from the flange of said removed therefrom, said nozzle together -sequntly elevated by water-pressure.
